There's a lot of thinly veiled dismissal and denial of neopronouns and non-binary identity. A lot of us can be very sensitive to it, more so than other people might be. Saying neopronouns are confusing might be true for some people but it's also said as a way of dismissing or belittling our identities.
Which is why a lot of mods on Blahaj communities are quick to shoot down that kind of rhetoric when it crops up.
